Where I grew up (suburbs in the Midwest in the US) it was common and expected all around that you'd leave your shoes just inside the door and walk around in your socks, at least for family/friends/guests. Can't remember about service workers.

Where I grew up (suburbs in the Midwest in the US) no one took their shoes off, ever, until it was bedtime. I cannot remember a single time taking my shoes of at a friend's house, or when visiting somewhere with my parents, or going off to see family. I guess the only exception would be if the shoes were exceedingly dirty, like you'd just stepped in mud or such.

Similarly in the military. We got un-booted at bedtime, and put them back on when we got up the next morning. Even in the barracks, including the nice ones that were reasonably nice apartment buildings, I never took off my shoes to walk around my room or when visiting someone else's (and vice versa; no one took off their shoes to visit me).

The first time I bumped into that rule was when I met my wife, who'd moved to the area from New York. I was quite confused when she asked me to take my shoes off at the door, and more than a little anxious. Sure hope I'm wearing decent socks and my feet don't stink, lest I be traipsing dirty feet around her apartment. To this day, I'm not convinced that hardsole shoes that haven't walked through wet messes are substantially dirtier than a damp sock that's been inside a shoe all day long.

I grew up in the suburbs in Ohio, the majority of my family and friends took their shoes off at the door.

I can't imagine feet in socks would be dirtier than the bottom of a shoe, but I guess it depends on where you walk, and how nasty you let your feet get. Like if you use a public restroom and then walk on carpets in your home, that's just gross. Maybe you walked in a park where dogs play. Good chance of tracking some dog shit into the house.

Absolutely no way. Like, it's not even comparable, sweaty smelly feet are infinitely cleaner than a shoe that stepped outside just once.

Even if we only talk about visible dirtiness (which is probably the least of the uncleanliness), I've hosted dinner parties in my flat where people kept shoes one and others where they didn't, and the difference is very very obvious: disgusting floors after the former and normally-clean-looking floors after the latter

Is this how most of the world operates? :-)

In the Nordics (SE, FI, NO, DK) it is pretty much the same. A large part of the year your shoes are a mess and you don’t want that indoors.

However, protective equipment is taken seriously and then shoes stay on. Here in Sweden, of course ordinarily all shoes are taken off (for 8-9 months of every year they're wet and dirty) but if workers come in to do some work, they keep their shoes on because they're protective equipment. If you're having them come during a particularly dirty time of the year, you may want to cover your floor with newspapers or give them shoe covers.

When I worked in Helsinki, it was quite common to see people do this in the office as well. Some people that were otherwise appropriately dressed (business casual) would be walking around on slippers. Always thought that was slightly funny. Very practical though. I had some rugged hiking boots that I wore in the winter there that definitely would come off when I got to work.

I've been in small offices where having slippers wasn't mandatory, but everyone brought them just because they were more comfortable. Also in one where taking your shoes off or using those medical plastic covers was mandatory (in spite of the work being IT).

Romania. Typing this at the office, wearing slippers :)

Yeah! Same for finland, the baltic states, or poland, or russia, or any country really where there is any kind of serious winter happening.

Eastern Europe is the same. I've only been in one house one time in the US where it was shoes off. It just felt wrong even though it wasn't carpeted and there were no rugs
